Granite (charnokite) question

One of my friends is interested to venture into Stone (http://g603.net) business. There is a spot of Granite (http://tanbrown.org) called charnokite found near his hometown in Ukraine. The pattern of the Granite (http://tanbrown.org) is black with green grains. The experts estimate the volume of the Granite (http://tanbrown.org) in this spot is at least 1 million cubic meters. We are curious about the mining method, the needed machinery and (http://maplered.com) the estimated price (USD/m3 or USD/m2) if sold in blocks, Slabs (http://www.VerdeUbatuba.com) or Tiles (http://www.g682.net) in Europe or USA.
If you can help please let me know.
